Automatic balancing of axial force: The reverse helical angle enables self-balancing of axial force, eliminating the need to rely on bearings for counteraction.
Extremely low bearing load: The bearings are hardly subjected to axial force, resulting in longer service life and simpler structural design.
High load-bearing capacity: The double-tooth meshing ensures a more even distribution of load, enabling the transmission of greater torque and power.
